Self-Heat Recuperation Technology for Energy Saving in Chemical Processes

Abstract

An innovative self-heat recuperation technology has been developed for heating and cooling thermal processes, in which not only latent heat but also sensible heat are circulated in a feed−effluent heat exchanger of the thermal process by compressing the effluent stream without any heat addition. Applying this technology to the thermal processes, the amount of energy required was determined using a commercial process simulation tool, PROII. The proposed self-heat recuperation technology, in which the heat of an effluent stream is recuperated and reused for feed stream heating by gas and/or vapor recompression, was found to drastically reduce the energy consumption.
